Abstract

Provided is a control unit of an oven. The control unit includes a board support panel, a first PCB, and a second PCB. The first PCB is installed on a backside of the board support panel such that heat from a heat source of the oven is blocked by the board support panel so as to reduce the heat on the first PCB. The second PCB is installed on a front side of the board support panel and may be a display PCB. The board support panel may be formed with resilient hooks to retain the PCBs.

Claims

1. A control unit of an oven, the control unit comprising:

a board support panel;

a first PCB (printed circuit board) installed on a backside of the board support panel such that heat from a heat source of the oven is blocked by the board support panel so as to reduce the heat on the first PCB; and

a second PCB installed on a front side of the board support panel.

2. The control unit according to claim 1, wherein the first PCB is a main PCB, and the second PCB is a display PCB.

3. The control unit according to claim 1, wherein the second PCB is coupled to the board support panel using a separate coupling member.

4. The control unit according to claim 1, wherein the first PCB and/or the second PCB are coupled to the board support panel using a hook.

5. The control unit according to claim 4, wherein the hook is formed on the board support panel.

6. The control unit according to claim 1, further comprising a front panel disposed on a front side of the board support panel.

7. The control unit according to claim 1, wherein the board support panel includes a seat groove in which the first PCB and/or the second PCB are seated.

8. A control unit of an oven, the control unit comprising:

a front panel;

a board support panel installed on a backside of the front panel; and

a main PCB installed on a backside of the board support panel such that heat from a heat source of the oven is blocked by the board support panel so as to reduce the heat on the main PCB.

9. The control unit according to claim 8, further comprising a display PCB on a front side of the board support panel.

10. The control unit according to claim 8, wherein the board support panel has a seat groove in which the PCB is seated.

11. The control unit according to claim 8, wherein the PCB is coupled to the board support panel using a hook.

12. The control unit according to claim 11, wherein the hook is formed on the board support panel.

13. A control unit of an oven, the control unit comprising:

a front panel;

a board support panel installed on a backside of the front panel;

a main PCB installed on a backside of the board support panel such that heat from a heat source of the oven is blocked by the board support panel so as to reduce the heat on the main PCB; and

a display PCB installed on a front side of the board support panel.

14. The control unit according to claim 13, wherein the main PCB and the display PCB are each coupled to the board support panel using a hook.

15. The control unit according to claim 14, wherein the hook is formed on the board support panel.

16. The control unit according to claim 13, wherein a seat groove in which the main PCB is seated is formed in a backside of the board support panel.

17. The control unit according to claim 13, wherein a seat groove in which the display PCB is seated is formed in a front side of the board support panel.
